Okay, I do consider myself somewhat competent. At least I can work on engines, electrical systems, etc. Yes, I can read a measuring tape, but .....

I had always gone on the assumption I was 18' 6" tall, as is stated in much of the literature. That made me 21' to the top of my antennas. I always felt as I was going under some low bridges that I had more room left than 21 feet would allow.

Well now I'm on the Great Loop and 17' really becomes a magic number (actually varies a bit with water levels) that will determine whether I can go through downtown Chicago to the Illinois River, or I take a less interesting route.

So I took a measuring tape to the boat in two different ways. Both measurements came up with exactly 17', but the books say 18'6". I have the standard anchor light on the radar arch, which is the highest point.

The boat is fully loaded as we are liveaboards. Also I am now in fresh water, so I sit a bit lower in the water.

I am so dumbstruck by this measurement that I just can't believe my own eyes. Why does everything say 18' 6"? Have I really lost my mind?

Oh, now I get it ... the 'I' was you *in* your boat.

Robert,
Yes, the I was meant to mean my boat! It always amazes me how we think we're communicating in a straight forward fashion, and we don't even come close sometimes. As well, I am always entertained by the humor that is presented on this site. Yes, I laughed out loud at your comment.

As a prior owner of a 4788 that did about 2000 miles of the great loop and doing this from memorey, my measurements were right at 18' 2" to the top of the light mast..........though we had a wind vane that was a bit higher than the light and I'm not sure if the 18-2 measurement was at the wind vane point or the anchor light??

Either way it was not near 17'................

Just how much beer DO you have aboard??????????

In any event, after the first bridge you will be ok.

Well, I cleared all the bridges through Chicago and on to Joliet. I unscrewed the lense of the anchor light and took out the bulb, which gave me an additional 4 inches to my clearance, thus 16 feet 8 inches. If someone else measured at 18'2", it must mean I just have too much stuff! I was full of fuel, water, have 300' of chain and three anchors, loads of tools, and all the stuff a live aboard would carry. I even cleared all the Joliet bridges (though they would have opened) that are rated from 16' 6" to 16' 9" at normal pool by going between the girders (I think I'm taking this new confirmation too far!). What a trip!

Well good, you made it.
Just wondering. Where is your water line? That should tell something about how much you are carrying.

Robert, he only feels 18' tall after drinking some of that beer.

Sorry, I couldn't resist. :(

Yes, it is interesting to note that the water line is right in the middle of the blue stripe when I am in fresh water. When I was in salt water it was a couple of inches lower into the white area below the blue line. My bottom paint starts below the blue line, as it should, where the water line would be in salt water. I think that the blue stripe put on by Bayliner must have been placed there for fresh water boats.

On my 38xx which is loaded pretty heavy including a 30 gal fuel tank for the outboard on the swim platform has the blue stripe well out of the water. There is a line below the stripe, then bottom paint. The line under the stripe is also completely out of the water and a couple inches of bottom paint is showing.
All may not be the same, just the way mine is.
